Hey there, I have this problem with the installation of Athena package on Mac Mojave :

Failed to build pgplot: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_graphics_pgplot/pgplot/main.log for details.
Error: Follow https://guide.macports.org/#project.tickets to report a bug.

I’ll be very thankful for any suggestion.
